Intel Desktop Board DG965WH Technical Product Specification 1.4 System Memory The board has four DIMM sockets and support the following memory features: • 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts • Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMS with x16 organization are not supported. • 8 GB maximum total system memory using DDR2 667 or DDR2 533 DIMMs; 4 GB maximum total system memory using DDR2 800 DIMMs. Refer to Section 2.1.1 on page 43 for information on the total amount of addressable memory. • Minimum total system memory: 512 MB • Non-ECC DIMMs • Serial Presence Detect • DDR2 800, DDR2 667, or DDR2 533 MHz SDRAM DIMMs • DDR2 800 DIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP) NOTE A minimum of 512 MB of system memory is required to fully enable both the onboard graphics and the manageability engine. NOTE To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the DIMMs may not function under the determined frequency. Table 4 lists the supported DIMM configurations. Table 4.
